摘要
在对涠西南凹陷L1段低渗透油藏启动压力和压敏效应进行研究的基础上,推导出了综合考虑启动压力和压敏效应的产能方程,并利用该方程研究了启动压力和压敏效应对L1段低渗透油藏注采井距和产能的影响。结果表明:低渗透油藏渗流规律研究不能忽略启动压力和压敏效应的综合作用,启动压力的影响比压敏效应更为强烈。
Based on researching the threshold pressure and pressure-sensitive effect of Member L1 low-permeability oil reservoir in Weixirnan depression,a deliverability equation was developed under consideration of the threshold pressure and pressure-sensitive effect, and then this equation was used to research the influences of the threshold pressure and pressure-sensitive effect on the injection production well spacing and deliverability of Member L1 low-permeability reservoir. The results have shown that the combined actions of threshold pressure and pressure-sensitive effect can not be neglected when researching the seepage flow pat- tern of low-permeability oil reservoirs, and that the threshold pressure has a stronger impact than the pressure-sensitive effect.
